What was your most favourite childhood sweet?
Do you remember Gambit bars? They consisted of two strips of chocolate, one plain and one milk, stuck together. Nobody else seems to have any memory of them. I suppose it’s possible that my subconscious has generated a novelty Eighties confection, but it does seem a little unlikely.

It wasn't two strips of chocolate though, it was one bar with two types of chocolate all mixed up.  It was sort of plain milk chocolate, or was it milky plain chocolate?  Either way, it was yummy and my life is incomplete without it.
